SPF stands for Sun Protection Factor, which measures how well a sunscreen can protect your skin from UVB rays—the type of ultraviolet radiation that causes sunburn. For example, an SPF 50 sunscreen theoretically allows you to stay in the sun 50 times longer than if you weren't wearing protection. However, factors like sweating, swimming, and towel drying can reduce effectiveness, so it's important to reapply as directed. Always check the label for instructions and remember that no sunscreen can block 100% of UV rays.

Even with high SPF sunscreen, it's a good idea to reapply every two hours, especially if you're swimming, sweating, or towel drying. Sunscreen can wear off over time due to water, friction, or simply being outdoors. For best results, apply generously before sun exposure and follow the directions on the packaging. Reapplying helps maintain your level of protection throughout the day.

Yes, many high SPF sunscreens are formulated for both face and body use. Some options are specifically designed for facial skin and may be labeled as "face sunscreen" or "mineral sunscreen." These tend to be lighter and less likely to clog pores. Always check the product label for usage instructions and consider doing a patch test if you have sensitive skin. If you wear makeup, look for sunscreens that layer well underneath.

Both spray and lotion sunscreens can offer effective protection when used correctly. Lotions are great for making sure you get an even, thorough layer, while sprays are convenient for quick application and hard-to-reach areas. With sprays, it's important to apply generously and rub in for even coverage. No matter which type you choose, follow the directions and reapply as needed for continued protection.

To remove sunscreen, wash your skin with a gentle cleanser and lukewarm water. For stubborn or water-resistant formulas, using a soft washcloth or a double-cleansing method (oil-based cleanser followed by a regular cleanser) can help. This helps clear away residue without irritating your skin. After cleansing, follow up with your usual moisturizer to keep your skin hydrated.
